[SOLVED] Yet another "ifreload -a" failed with exit code 1

Update: I believe I have figured this out. Unfortunately this was a self inflicted issue due to an internal SD-CARD that had my previous install becoming re-enabled (a bios default) after a cold boot when I was cleaning the inside of the server. This was the initial install for my migration from VMWare to Proxmox and the SD-Card was only 16G and I forgot all about it until it ran out of room <insert facepalm>.

TLDR: I was an idiot and didn't check my bios boot drive settings after a cold boot. This caused me to repeatedly boot into a broken install on an SD-Card over and over and over and over again thinking I was booting into a fresh install.
 
Sad to report that the same error message occurs. Screenshot attached.
Sorry to reply here, but I'm having the same issue :( how did you solve this error
(i can't install vlan #apt install vlan, because it wants to delete pve as it's integrated in there already)

I'll try reinstall it again..
